gmdate() in function parameter gives parse error

[cowboy]

I'm using PHP 5.3.5 with Fast-CGI.When I try to use \[code\]gmdate()\[/code\] to set the initial value for a parameter, I get the following error:\[quote\] Parse error: syntax error, unexpected '(', expecting ')' in MyClass.php on line 3\[/quote\]Here's my code (line 3 is the line where myFunction is declared):\[code\]function myFunction($myDate = gmdate('Y-m-d')) { // ...}\[/code\]Am I doing something wrong? Is this a bug? This also occurs if I do the same thing in a class function.
